Be it known thatI, W. 0. TUBES,oi'-Spring,'A

inthe county of Crawfordand Stateof Pennsylvania, have invented certainnew and vuseful Improvements inA a Mowing-Machine, oi' which thefollowing isa full,iclear, and exact description, reference being hadtothe accompanying drawings,` whichlmiake part of this specification,and in which-y 1 [Figure 1 isaperspective view of a mowing- .shows asection of the' shoe and `fiu,g ;er.i )ar.

my machine standing upon two drive-wheels, A, whichv are connected' bythe axle B, and

which, when turned forward, cause the axle B to revolve with thembymeans of two ratchets, d, which allow aback'ward vmotionwithoutrotatingvthe aille. That part of d which is shown in Fig. 6 ispermanently' attached to the drive-wheels A, of which' it# constitutes aThe parts of Fig. 6 shown at n and o to work smoothly, forming 'theother-half of lthe-clutch to the ratchet.

Figs;` 6 and 7 are iitted so as to worksmoothly together, the slides fgbeing held against Fig. 6 at z by means of springs, as showuin Fig. 8,thus Fig. Qshows the frame upon which the gearing ismounted..-vFig-ldshows aaseltl` Fig. 13 shows anfinverted view ofdrivers seat and fastenings.

forming'ashoulder-ratchet. 'lhus the forward motionof the drive-wheels Ais communicated to the axle B, upon which is fastened the camwheelE,'a'rmed withV twenty-tive cams. The cam shown at E, 'drivenforward,:acts upon the roller F, causing the rocking beam G to recede,driving a correspondingroll'e'r on the upper end of the rocking beain,as shown in Fig. 16,

between :two cams'on the opii'osite side of the 12, which shows asectionof the sliding'head andaxleB.-. Fig. 16.v shows atopzviemofLthe.

rocking beam G and rollers F, with .sli-ding headH and guide I, which isfastened to the frame K, under which Hpasses, and is held in proper`position and` is pivoted toth-e'pit- -manDthe'othe'r end ofnwhich isiconnected in like mannerl to the bent levers,-which isarmed with a longfinger reachingwout upon the pit-` .man, the point of which is shown atD, allow- Aing it to drop but a little below a horizontal.

The lever s is pivoted tc Athe upper part oi' the bearing-box C, turningan acute angle at that point, passes up near the corner of the driversYseat V., so that he may readily move itwhen desired. Ii' he moves'thelevers from him, he draws backl the sliding head H, to which is attachedlthe rocking beamaG, relieving therollers F from contact with thecam-wheel E, throwing the machine out of gear. 4A reverse action on thelever s put-s the machinein gear. .The pitman D, falling a little bellowa level at s, remains a firm brace, keeping the rocking beam G in properposition.

' V., is the'drv-ers seat, vunderneath of `which is the spring Z,resting upon the guide I. Fast, ened upon the upper end-fof the spring Zis a square board,u,hinged to the front edge of the seat V, as shown inFig. 13. Fig. 14 is a top. view 'of the square .board u.

q represents-notches, in which 'the back end of the bentlever b, asshown in Fig. 15, catches. If Fig.,` l5 be brought forward and thestraps p hinged with those ou Fi'g. 14, Fig. 15 then also iorm theguides to the cuttert.

` bronghtover upon Fig. 14, they will be in order for operation, thelever b raising or lowerthe seat as it is moved.

The bent lever W, working in the jaws V f and upon the plate c, whendrawn back, raises" the machine from its inclination vto a parallel 1with the tongue T.l The tonguel is hinged to the frame K,'and may bemoved to the right orleft,causingm`uch or littlesidedrai't. Italso worksop and down freely in the guide U. vThe f'. fratne K, upon which thegearingis mounted,` is swung under and hangs upon the axle Bl b'yf meansof the bearing-boxes It also has vtwo pivots, as s'hown in Fig. 9 at K,which workiin the plates in Fig. 10, (shown vat: J.) The frame J,passing around .the frame K, worksupon its pivots,.'as s hown inFig'.'11 at J K,

which are directly beneath the rocking beam -I.t is also supported'bythe stirrup M,

which leaves it free to work up and down, except as slightly preventedby the spring L.' rlhe 'nger-barN is secured to the lower extremity ofthe frame J which readily adjusts' it to the ground by meansof'the'sustaining-A shoe f. Fig. 4 shows aninver-ted view of then'gerfbar, across which and near the end is secured the b'ar m,projecting a little in front and fitting closely in the nortisel, (shownin Fig. 3,) securing thev bar N, as shown in Fig.

2. v m being pressed down'into the mortise l,

'N will `tit in the bed y, the lever `e being fbrought down .restsuponthe ger-bar N as shown in Fig. 1, securing it in its heel-socket.The guardteeth are so constructed that they f pass under and overtheibar N, both forks fastening withaa single bolt, as shown-atj. They Vhis a concave device for track=clearing, re-V sembling .the mold-boardof a. plow, and is made of sheetiron, of which Fig. 5' is an invertedview.

Thefrictionroller a, working in the jaws S,

is back 'of and supports the cam-wheel E, there 'being-a. correspondingone on'the. opposite side.

The guides O,- by which the rocking beam G is made'to traverse in itsproper line, is fast-1 ened firmly tothe frame K--tbe front onedirectly, the back oneby means of a block shown at Q.

The letters'ar show a device for carrying iinger-barvvhen detached frommachine.

R is the drivers. foot-rest, upon which the .plate c is fastened. l

Having thus full-y described the construction and operation ot' myimproved mowingmachine, what I claim therein as new,- land desire to'secure by Letters Patent, is- 1. Fastening the heel end of thefinger-bar iny its socket in the sustainingshoeby means -of the levere,combined with said .'shoe, substantially in the manner and for thepurpose shown-.and described.

2. The arrangement of the-'bentlever s and pitu'xan l), incombinationvwith' the sliding head H- and rocking beam G, for thepurpose' of throwing said beam in and outot gear with the cani-wheel Eland firmly bracing the same when in gearsubstantially as described.

3. The employment of the bent lever b, -i-n combination with vthedrivel-s seat Y and its support, lin Athe manner and' for the purposede'- scribed. v
